Anyone can use Sovrin without being a Steward–but Stewards have unique access to their own central node on the ledger, which may improve performance of tools and services they build. Stewards also have a say in how Trust Anchors are created, which in turn unlocks ordinary identities that the Stewards may especially want to promote. Plus, Stewards acquire some gravitas and reputation in the network for their efforts. Thus, Stewards may find that this status furthers their mission in valuable ways.
